我对数据库中的元素有疑问。 我有3张桌子：
prenotazione（id，nome_rich，cogn_rich，email_rich，oggetto_rich，data_richiesta，orario_richiesta）
interni（nome_int，cogn_int，email_int，id）
esterni（nome_est，cogn_est，email_est，id）
在我的索引文件中，用户可以添加多个选择字段（“ interno”和“ esterno”）。
我的问题是我想将“ richiedente” ID连接到所有“ interno”和“ esterno” ID，以便当我打印“ richiedente”的某个ID时，它还会打印所有已连接“ interno”和“ esterno”的ID。
目前，我已在序列号中设置了“ interno”和“ esterno”的ID（我使用Postgres），因此，当用户提交表单时，例如，“ interno”和“ esterno”具有3个不同的ID
我粘贴我的代码： index.php
